Linqpad 5 How To Insertupdatedelete DataIt did take a while, however, to look through the numerous sample scripts and figure out exactly how to insertupdatedelete data, so I thought I would share what Ive found.The biggest changes between working in LINQ-To-SQL in a Visual Studio 2008 project and writing a LINQ query in LINQPad are the lack of a DataContext, the difference between C Expressions and C Statements, and the addition of a Dump command. This data context is in charge of maintaining your database connection and is what you use to submit changes to the database. Because there is no data context readily available to you (and no.dbml file) in LINQPad, the way you go about this is slightly different. There is a globally-scoped subroutine, SubmitChanges(), that should be called whenever you wish to commit an action to the database. In this mode you can type a simple query like from r in Regions select r and run it to see the results. By switching to C Statement(s) mode you are able to declare variables, control flow statements, and reference objects; this is the mode you need to be in to insertupdatedelete data. Because C Statement(s) mode gives you the capability to run many queries in one execute, displaying the results of those queries must be manually invoked. To do so simply call the.Dump() method on the resultset of the query you want to display..Dump() is implemented as an extension method available on all objects, so whether you are retrieving a single object, a list of objects, or an anonymous type the Dump method will be available to display your data.
